A few minutes ago I went to the NAA web site to find the weight of my NAA 22 mag for another thread, anyway I noticed this
North American Arms offers a .22 Conversion Cylinder for our .22 Magnum Mini-Revolver. The Conversion Cylinder is a special longer .22 Long Rifle cylinder that will fit in your .22 Magnum Mini-Revolver

What would be different, I have never shot 22LR through my 22 mag cylinder, but I wouldn't have thought it would be unsafe, am I wrong? If not why the "conversion cylinder?"

To see the link go here and look at the bottom of the page.
 
.22 Mag is not simply a longer .22 LR. The dimensions are different enough to require a different cylinder. .22 Mag is a scootch larger in diameter.
 
Shooting .22 LR in your .22 Mag cylinder is not a good idea. The brass case is smaller in diameter and can split. I have done it with mine to see what it would do. I got away with it, but it spit trash much worse than the mags did.

It's like in Smokey and the Bandit. You can think about it.....but don't do it. :)
 
how accurate are your NAA pistols? I've only shot mine a few times...I guess it takes some getting used to, especially with no rear sight.

maybe I should put a scope on it :)
 
Well, I've been educated. I always thought the only difference in the two were the length. Is the actual projectile the same? I would think it would be but I've been wrong before........obivously. Learn something new everyday.

As for the accuracy question, I can hit a homemade 6x8 plinker in my front yard about 12-15 yards away, that is all I can really tell you. And for the record I use the notch for the hammer as a rear sight, don't really think that's what it is for but hey, works for me.
 
The .22 mag bullet is seated like any other straight case bullet, into the brass and crimped. The .22LR OTOH is a healed bullet, back of the bullet is smaller in diameter and fits into the brass. The .22LR is externally lubricated. The .22 mag is as with any centerfire for lubrication, but is usually jacketed rather than plated or lubed lead. But, the heal crimped nature of the .22LR means the bullet is the same diameter as the case where the .22 Mag, the case is larger than bullet diameter as the bullet is pressed INTO the brass. Look real close at 'em and you'll see what I'm talking about.
 
I have a couple of questions about these revolvers and would hate to make a fourth thread about them to ask, so I'm just going to ask here.

I plan on getting a .22lr one for pocket carry, just something small for when a full sized revolver wouldn't work. Are there any good .22 defense rounds out there? Would they be safe for this small gun?
 
ruodo,

you can check out the ballistics on the american arms page. I'd check into the 22 mag... quite a bit more velocity over the 22LR... but it's fricken loud...
 
The first time I shot my 22 Mag NAA, it was in a indoor range between the two walls of a lane. I thought I blew up. I felt a blast of wind and heat hit me in the face and zap under my glasses. I slammed my eyes shut and then cautiously looked for my hand.

I'm not exaggerating. I shoot big handguns and this one was a giant boom. It also can have a great flash. It's like the little cricket from MIB.

That is what my 2 kids call mine, "Cricket" The oldest (10) shot it the other day for the first time and just loved it.

For carry use, get yourself a 22mag instead ... it's a whole different kettle of fish from the 22lr, and the handgun is no larger. My daily carry is an NAA BlackWidow in 22mag, pocket holster in my right front pocket. Don't hardly even know it's there.

Recoil of a 22, "bark" of a 45. :evil: And a lot more "bite" to go along with that bark than most people give it credit for.
 
.22 mag barks because it's designed to be shot from a rifle. You don't get that much extra umph out of it from a sub 2" barrel. It ain't that much more caliber, don't bet your life on it, put it that way. I never carry my .22LR version as a primary. I have, on rare occasion, and I didn't feel good about it, but it was forced on me by dress and circumstance. I always carry a 9x19 or a .38 in a pocket and I'm lookin' to get a Ruger LCP as my next gun so I'll never have to settle for a .22 as a primary again. :D

The little NAAs are fun, unique, small, can do things you wouldn't give 'em credit for, but as a primary defense gun? Nah. You need one though, just because. :D I mean, it COULD save your life in a pinch, but just imagine getting into a gun fight and this is all you have. Scary thought, ain't it?
 
Yes, but imagine getting into a gun fight and having nothing at all. Yes, it's a BUG. I'm a touch leary of the 380 BUGs. None have a really good rep.

Now, you should see my 22S NAA - it is so cute.
 
Yeah, mine's cute, too, but I still want an LCP or P3AT. I like the little NAA a lot, though, for just backup. If I had to resort to it, I'm thinkin' 1) I've found cover by then or 2) it's that hand to hand thing that was mentioned and my right arm his fending him off while my left is free to grab the .22 which at that range is quite a formidable weapon.

I can say, these little revolvers are amazingly finely built, like little Rolexs that fire bullets. :D A P3AT or LCP is crudely put together by comparison. They do work, though, and occupy a size and power niche I feel compelled to fill in my collection. I was just at Academy and low and behold, but they had an LCP on display. Price? $349. OUCH. That's about 30 or 40 over MSRP? I think I can wait for the supply to catch up, well, if it ever does.:rolleyes:
 
Would the heavy 60g Agelia SSS rounds work well as a SD loading?

I have no idea of the vel. you could get out of such a short barrel but the bullet might have a better chance at penetrating versus a light 32g one.
 
I have 2 NAA that came with both cylinders

I ordered 2 NAAs in about 1991, one for me and one for the wife. They came with both 22 LR and 22 mag. cylinders. I have never put the 22 LR cylinder in either. The 22 mag is so loud you think the gun blew up but does not kick bad. Like has been said, it is a lot better than nothing. I carry mine EVERY day.

I have several NAA mini revolvers. Very well made little guns that are fun to shoot.
 
Has anyone actually chronographed the .22 mag in a sub 2" barrel? I'm sure it's a little hotter, just not hot enough for me to carry it as a primary any quicker than I carry the .22LR. I'm happier with my 9x19 which pushes a 115 grain .355" JHP at 1262 fps chronographed from a 3" barrel.

The .22 is woefully inadequate in penetration. I shot a dense oak 1x4 with mine and it didn't penetrate through. I could see the bottom of the bullet in the board. :rolleyes: But, screw that thing in a guys ear and it'll stop a fight, I'm quite sure of that.

If those figures from NAA are correct, probably are as the rifle shoots around 2000 fps, that's 142 ft lbs assuming a 40 grain bullet. Thinkin' the V Max is 32 grains and that would be 114 ft lbs, about the energy of a .32ACP standard ball which I don't think much of, either, and considering the .32 fires a 60 grain bullet, it'll probably penetrate better.

Here is some performance data for ya:

http://www.brassfetcher.com/22WMR.html

Plenty of these are from NAA Mini's. Not going to get -anything- like that from 22lr.
-----------------------------------------------------------
Firearm : North American Arms .22 Magnum revolver with 1 1/8" barrel

Ammunition : Various .22 Magnum

Calibration : all depths corrected depths

Shots were fired at 10" distance from the block - as such, impact velocities were not recorded.

Shot 1 - CCI Maxi-Mag HP +V 30gr, penetrated to 11.4". No expansion/deformation present.

Shot 2 - Winchester 40gr Semi-jacketed hollowpoint (part #X22MH), penetrated to 10.6". No expansion present.

Shot 3 - Winchester Supreme 34gr JHP (part #S22WM), penetrated to 11.0". Minimal expansion of copper jacket took place, no deformation of the lead inner core.

Shot 4 - Remington 40gr JHP (part # R22M1), penetrated to 9.0". No expansion present.

Shot 5 - CCI 40gr TMJ (FMJ bullet), thru penetrated the 16.0" block and was not recovered - estimated penetration depth was 12.5" plus some.
 
These velocity numbers are old (ancient, even) but they still should be valid.

Ed Matunas tested these mini revolvers for his 1984 Guns and Ammo special .22 Rimfire edition magazine.

With the NAA .22 short model, 1 1/8" barrel, he got 795 fps with a 29 grain bullet, for 41 foot pounds of energy, for 47 fpe.

With the NAA .22 LR model, 1 1/8" barrel, he got 730 fps with a 38 grain bullet, for 46 fpe.

With the NAA .22 Mag. model, 1 1/2" barrel, he got 925 fps with a 38 grain bullet, for 76 fpe.
